West Nile Virus

Increases in West Nile Virus cases have some parents concerned about their children’s health while at school. The West Nile Virus is spread by mosquitos carrying the virus. People can avoid mosquito bites by limiting their time outside during dawn and dusk, prime times for mosquitos to feed. These are typically times when students are not at school.

DEET is the active ingredient in insect repellants. DEET is listed as N, N-diethyl-m-toluamide or N, N-diethyl-3-methylbenamide on products. Insect repellants containing DEET can be harmful if misused or overused. Parents should keep the following in mind:

• Follow label instructions and check for the DEET concentration and length of effectiveness.
• 30% DEET is the maximum concentration that should be used on children and infants.
• Do not use DEET on children under the age of 2 months.
• DEET should not be used if in a product that combines the repellent with a sun screen.
• Sun screens often are applied repeatedly because they can be washed off. DEET is not water-soluble and will last up to 8 hours. Repeated application may increase the potential toxic effects of DEET.
• Apply DEET sparingly on exposed skin; do not use under clothing.
• Do not use DEET on the hands of young children or spray on the face; avoid applying to areas around the eyes and mouth.
• Do not use DEET over cuts, wounds or irritated skin.
• Avoid spraying in enclosed areas; do not use DEET near food.

Applications of DEET products at school should be treated the same as other over-the-counter medications. School nurses should be consulted, and refer to the school’s over-the-counter drug policy prior to students using products from home.
